I didn't say you had a duplicate queue.  You have two declarations of
the same queue with conflicting parameters.  From what you said, it
looks like one declaration is done by you manually in "the web
interface" (I don't know what that is), and the other is possibly done
by Spring AMQP via RabbitAdmin (I'm guessing here too).  You should
probably just pick one of those and stick to it, but if you want them
both to work you have to just use the same parameters in your Spring
config as you did for the manual declaration (probably only you know
what they are).  Assuming I am right: to switch off the Spring auto-
declaration, you need to set auto-startup=false on the RabbitAdmin; to
switch off the other declaration you just have to not do it.
